21 Atlantic Street - truly a one of a kind. A fixture of Rockland's South End for over 100 years, she has seen the neighborhood transform from an industrial working waterfront to a beloved and walkable seaside neighborhood becoming one of the most desirable locations in the Midcoast.

Up the reimagined modern staircase you find 3 of the 4 bedrooms including the luxurious Primary Bedroom Suite.

The ''Pool House'' also features a top floor bedroom with a huge slider to the roof deck and, in our opinion, the best bedroom view in all of Midcoast Maine - literally the ''cherry on top'' of this singular propert
